Despite the global financial crisis, Qatar has prospered in the last several years - in 2010 Qatar had the world's highest growth rate. Qatari authorities throughout the crisis sought to protect the local banking sector with direct investments into domestic banks. GDP rebounded in 2010 largely due to the increase in oil prices. Economic policy is focused on developing Qatar's nonassociated natural gas reserves and increasing private and foreign investment in non-energy sectors, but oil and gas still account for more than 50% of GDP, roughly 85% of export earnings, and 70% of government revenues. Oil and gas likely have made Qatar the highest per-capita income country - ahead of Liechtenstein - and the country with the lowest unemployment. Proved oil reserves of 25 billion barrels should enable continued output at current levels for 57 years. Qatar's proved reserves of natural gas exceed 25 trillion cubic meters, about 14% of the world total and third largest in the world. Qatar's successful 2022 world cup bid will likely accelerate large-scale infrastructure projects such as Qatar's metro system and the Qatar-Bahrain causeway.
